SPI NOR core changes:

Browse source 
- move vendor specific code out of the core into vendor drivers.
 - unify all function and object names in the vendor modules.
 - make setup() callback optional to improve readability.
 - skip erase logic when the SPI_NOR_NO_ERASE flag is set at flash
   declaration.
